TRUCK.

To aZZwfio m it may concern:

,Be it known that 1., JAMES D. TAYLOR, a citizen of the United States, residing at Portland, in the county of Multnoniah and State of Oregon have inventedn new and useful Truck, which the following is a specification.

This invention relates to trucks for elevating and moving heavy articles; the truck which is the subjectof the present invention being designed more particularly for moving It is the oh 1; of the invention to provide a truck for rhis purpose, which is small and compact in form so that it can slide under the safe, and also'io provide a structure by which a truck of great strength is had so that it can successfully withstand the strain of the heavy load which is placed. upon it.

A. further object is to provide the elevating device of the truck with a burn table, so that the position. of the safe may he changed When on the truck. I

The invention also has for its object to provide an easily operated elevating means, together with other novel and improved. s ructural details to he hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a front elevation of the igruclc showing the same in use. Fig. 2 is an enlarged transverse section of the truck. 3 is a plan view partly hrolcen away. Fi 4- is an enlarged front elevation.

The truck frame comprises a pair of spaced parallel extending angle beams 1, and a plate (3 mounted on the horizontal portions of said beams. The angle beams are braced. by angles 2, which carry the axles 3 of the truck wheels l. said xlcs being carried by he per iendicularly exliciul'ing portions of the angle beams. The truck wheels may he provided with a rilhher tire 43*. The plate 6 has a central enlargement '3 provided with a screw'thrcaded opening in which the elevating screw is threzuicd. The screw udapted to travel up and down in this openmg; and carries all; its upper end a turn fhhlc Q'on which the load placed.

v The angle lveams l carry lli lheir ends I- heams and (he latter sup iiort a stationary platform '7 having an opening" 7 through which (he elevating screw and the iurn lahlc loosely pass.

The means for rotating ihe elevating screw 8 comprise 21 hovel gear 10. and a phi- Specification of Letters latent.

ion 12. in mesh therewith. The gear 10 is secured-lo the screw by a spline 11, so thatit may rotate the screw in the threaded opening of the enlarged portion 6 of the plate 6. The screw is adapted no travel up and down in said opening when the gear lO-is rotated. The enlargement 6* extends below the plate 6, and is shaped to in in a support on which the gear 10 is mounted. for rotation. The upper end of the gear carries a ring 13 which seals in a groove made in. the outer surface of the enlargement, and which provents thegear from traveling with the screw.

The pinion 12 is mounted on a shaft 14- passing through an opening in one of the beams 1, and journale'd in a bearing 15 mounted on the outer face of said beam. The shaft projecis a short distance from this hearing, and the projecting end is squared for connect-i on of an operating device, which may he a ratchet lever.

In use, the cruel: is rolled under the safe 16 To be moved, an d the elevating screw 8 is operated to raise the sai eoil the floor. after which it may carried by the "truck to the place desired. Between the bottom of the safe, and the top of the platform .7 are placed wedges 17 to balance the safe on the truck. The .afe is supporlied directly on the turn table which enables it to be swung around while on ihe liruck.

By the structure herein described, a truck" is had which is strong and din-able, and which therefore can successfully withstand the strain placed upon it by the heavy load which it carries, the elevating screw is easy to operate, and the invention therefore offectually serves the purpose for which it is designed.

\Vhati s claimed is:

1. A truck comprising a wheeled frame having a threaded opening. a traveling eh val'ing screw working in said opening, a platform mounted on the frame, and having an opening through which ihe screw adapted to pass; and means for o oral ing the screw.

2. A truck comprising a wheeled frame havinga threaded opening. a traveling clevating screw working" in said queuing, a. platform, niounlcd on the ironic. and having an opening through which (he screw is adapled to pass means for operating the r crmv, and a lIllTI'hlfiblG mounied on he working end of the screw.

3. A (ruck co 'i'iprising" 5:. ti rnuw comiislinn of side hznnis. a. plate mounind Liwt'ron. and

formed with a central enlargement having a threaded openlng, and a stationary platform "mounted on said plate, an elevating screw threaded through the opening, and means for operating the screw, the aforesaid platform havingan opening through which the screw is adapted to pass.

4. 'A truck comprising a frame consistm of side members composed of spaced paralle angle beams, and: a plate mounted on the horizontally disposed portions of said beams,

said plate-being formed with a central en:

largement having a threaded opening, wheels carried by the perpendicular portions of the angle beams, an elevating screw threaded through the opening, means for operating In testimony that I claim the foregoing as my own, I have hereto-afiixed my signature in the presence of two witnesses. v
